I have recently separated from my husband of 12 years. To summarize it briefly, he is a binge drinker, and recently, I discovered, he has started gambling. He is also anti-social and keeps to himself all the time. I suggested that we separate, and I am happier. Our 3 kids also seem happier. My husband phones me on an average of once a week, and wants me to reconsider the separation. I feel better being separated, but I still feel like a failure. Why is that?
